I work as a Sales Agent for the Talon Protection Group (talonprotectiongroup.com) but the knife is handy for lots of purposes.
Work frequently calls for me to visit nasty neighborhoods in a shirt, Sports Jacket and slacks. I often carry one of my OTF blades with a Stiletto-type blade. More often, I'll carry an OTF with a drop-point blade. (I'm not above stabbing a miscreant that insists upon molesting me, or my female co-worker). Downtown Portland, Oregon can get extremely "dicey"... even on a weekday morning!
I'm looking for a vertical shoulder rig I can wear to carry this dagger into "harms way" while dressed for business.
